For those impatient here is a line from there: "I Love mod_perl, I Want to Know Who Wrote This Great Free Product!
Well, Doug MacEachern is the person to blame :).
He is the guy who gave mod_perl to the mod_perl community.
He is the Linus of the mod_perl project."

"Many people wonder and ask "How much of a performance improvement does mod_perl give?".

Well, it all depends on what you're doing with mod_perl and possibly who you ask.
Our friends at Sun Microsystems saw a 400% improvement over CGI.However, these tests were done with a _very_ small script where perl start-up time was not a factor.

How much of a difference can this make? It all depends, Andreas boasts a 2000% improvement over CGI!
The best way to measure is to try it and see for yourself!"
